TEST-SCALE FOR MALTSTERS.

SPECIFICATION forming part of Letters Patent No. 694,781, dated March 4,1902.

Application filed July 12, 1901.

To all whom it may concern.-

Be it known that 1, WILLIAM H. PRINZ, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Test-Scales forMaltsters; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a test-scale formaltsters, the object being to provide a scale by means of which themaltster is enabled to determine when his grain has been sufficientlysteeped and to determine the subsequent loss in weight sustained in themalting process; and it consists in the features of construction andcombinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is aside elevation of the test-scale constructed in accordance with myinvention. Fig. 2 is a central longitudinal section, on an enlargedscale, of the grainreceptacle forming part of my scale. Fig. 3 is afragmentary detail side elevation showing the manner of securing thecover on said receptacle.

My said scale consists of a base A, carrying spirit-levels B and O andresting on set-screws D, by means of which it may be leveled. Mounted onsaid base A is a standard E, bifurcated at its upper end and providedwith openings F in said bifurcated portion to receive the knife-edgepivots G of the scalebeam H. The latter is provided at one end with athreaded shank I, adapted to receive a tapped weight J and at its otherend is enlarged and provided with a longitudinal slot K. Above said slotK and between the ends thereof said scale-beam H is provided with agraduated scale L, indicating percentage and reading from O to 100,beginning at the point nearest the pivot. Immediatelybelow said slot andoccupying the same position relatively thereto is a graduated scale M,indicating ounces, marked 0 to 12 and reading in the same direction assaid grad uated scale L. Below said graduated scale M is anothergraduated scale N, also indicating Serial No- 68,022. (No model.)

percentage, but reading in the opposite direction from the scales L andM. Aweight O is movable on said scale-beam above the slot K, and aweight P is movable in said slot, both said Weights indicating on thegraduated scales with the edges farthest from the pivot. On the otherend of said scale-beam a hook Q is hung, which is adapted to receive andsupport a perforated receptacle R, adapted to contain the grain to beweighed and tested. The said receptacle R isprovided with a bail S,pivotally mounted thereon and with a flanged cover T, the flange ofwhich is provided with L-shaped recesses adapted to receive the pivotsof the bail and to be held in place thereby. Said cover is also providedwith an internallyt-hreaded nipple U, adapted to receive the threadedend of a hollow handle'V, by means of which said receptacle may be hungin a steep-tank or inserted in the body of grain being malted. I providean arm IV in said base, having an upwardly-extending slotted portionadapted to receive the outermost end of the graduated portion ofscale-beam H and limit the motion thereof in both directionsin the usualmanner.

After leveling the scale the receptacle B, after receiving athermometer, is hung on the hook Q,-the weights 0 and P are moved untilthey stand at 0 on the graduated scales L and M, and the weight Jadjusted until the scale-beam H balances. The weight P is then moved toindicate 12 on the graduated scale M and grain is then introduced intosaid receptacle R until the scale-beam again balances. The receptacle Ris then removed, the handle V secured thereto, and said receptacle isthen inserted in the water in a steeptank together with the body ofgrain to be malted.

The maltsier determines from examination of his grain the amount ofmoisture it must absorb in the steeping process, and by removing andweighing the receptacle R and its contents at intervals he can readilydetermine when the desired percentage of moisture has been absorbed. Toeffect this, the handleV is removed, the receptacle is again hung on thehook Q, and the weight 0 moved up on the graduated scale L until thescale-beam H again balances, the weight P remaining in the positionshown in Fig. 1. Then said scalebeam balances, said Weight 0 willobviously indicatethe percentage of gain in weight, and

hence the amount of moisture absorbed by the grain. After attaining thedesired percentage of moisture the grain is transported to themalting-fioor,where germination takes place. During germination thegrain loses weight by losing moisture and by the liberation of gasesduring this process, and by frequently weighing the grain in the saidreceptacle (which remains inserted in the body of grain during thegermination) the maltster can readily determine the rapidity andprincipal periods of loss in weight. As such weight is lost the weight 0is moved gradually back until it again indicates 0 on the graduatedscale L, and thereafter any further loss in weight is indicated by theweight P, which is gradu: ally moved toward 0. on the graduated scale Mand simultaneously toward 100 on the graduated scale N, thus indicatingin ounces and percentage the loss from the original weight. 1 a

I claim as my invention 1. In a test-scale, the combination with a baseand astandard,of ascale-beam fulcrumed between its ends on said.standard, one end of said scale-beam being provided with two graduatedscales indicating percentage, and reading in opposite direction, andwith a graduated scale indicating ounces,a weight movable over andindicating on one of said percentage-scales; a second weight movableover and indicating simultaneously on both the other graduated scales,an adjustable counterweight on the other end of said scale beam, and aremovable perforated receptacle on said other end formingaload-receiver,substantially as and for the purpose described.

2. In a test-scale, the combination with a base, a standard thereon, anddevices for leveling said base, of a scale-beam fulcrumed between itsends on said standard, a longitudinal slot in one end of saidscale-beam, a graduated scale on said scale-beam above said slotindicating percentage, a similar graduated scale below said'slot readingin the opposite direction, a graduated scale below said slot indicatingounces, a weight movable over and indicating on said first-namedgraduated scale, a secondweight movable in said slot and embracing thelower bar of said scalebeam and indicating simultaneously on both saidlast-named graduated scales, an adjustable counterweight on the otherend of said scale-beam,a removable perforated receptacle on saidlast-named end adapted to receive the substance to be weighed, andcoacting with said counterweight to balance said scale-beam,substantially as and for the pu rpose described.

In testimony whereof I afiix my signature in presence of two witnesses.
